I tend to avoid arguments regarding things that are completely opinion based, unless it is for the sake of discussing for the sake of discussing. Sometimes it is fun to argue certain things, even with both parties knowing there is going to not be any changing of minds going on. (Except in fights against Sasuke. The fact that Sasuke can literally change minds with his genjutsu means he automatically wins all fights by default. Goku would definitley lose, but Android 16 might pull off a win if he's lucky, Toph from Avatar would probably kick Sauske's ass unless he can pull of a genjutsu that works through vibrations in the ground. I don't care how canon it is, any talk about SPECIFICALLY EYE-BASED GENJUTSU WORKING ON THE BLIND IS COMPLETE AND TOTAL BS)
Hell, the only time I ever feel like I HAVE to argue is when saying something as a fact, but that fact is clearly wrong. Not the same as giving out an opinion as if it is established fact, even though I could still try and argue that as opinion despite how futile such arguing will prove to be. I bet people call me a know-it-all behind my back, but if not being called that means going around and "pretending" I do not know when someone is passing about information that is clearly incorrect, then to hell with what people think of me! I personally only care about WHAT is right, not about WHO.
